No. 429,440 Claims priority, application Netherlands,Feb. 29, 1964, 6,402,050 4 Claims. (Cl. 220-4) The invention relates toa vacuum cleaner comprising a housing consisting of at least two partsand a handle which is rotatably secured to one of the parts of thehousing and which is provided with means for detaching a latch or lockjoining the two parts of a housing so they can be separated by linearparting movement and likewise reunited.

The invention will now be described more fully with reference to theaccompanying drawing, in which:

FIGURE 1 is a perspective view of a vacuum cleaner in accordance withthe invention,

FIGURE 2 is a longitudinal section of an embodiment of the invention,

FIGURE 3 is an elevation of a second embodiment of the invention, viewedfrom the inside (the wall of the housing having been removed partly),

FIGURE 4 is a section taken on the line IV-IV of FIGURE 3,

FIGURES 5 and 6 represent details of the construction shown in FIGURES 3and 4,

FIGURE 7 shows a variant of the second embodiment,

FIGURE 8 is a section taken on the line VIII-VIII of FIGURE 7, and

FIGURE 9 shows a detail of this embodiment.

The vacuum cleaner comprises a housing consisting of two parts 1 and 2,the part 2 being provided with a suction opening 3, while an exhaustopening 4 is provided in the part 1. The part 1 comprises the motor andthe impeller which partly extend into the part 2. The part 2 comprisesthe dust bag which may be secured to the part 1.

A carrying strap 5 is secured to the part 2. The points of rotation ofthis strap are located on either side of this part in a protuberance 6which is prolonged along the side wall of the part 1, and which alsoaccommodates the means for joining the two housing parts together.

The carrying strap extends through the slot 7 of the protuberance 6.

In the embodiment shown in FIGURE 2, the carrying strap 5 is rotatablysecured around a pin 8. The means for joining the two housing partsconsist of a pin 9 secured to the edge of the housing part 1 or to theedge of the protuberance 6 and of a strap 10 which is secured to thehousing part 1 and the bent end of which is adapted to snap across thispin. The end 12 of the strap 5 bent around the pin 8 is provided with astop 13 which, when the strap is moved to the right-hand side, may getinto touch with a stop 14 secured to the strap 10 and which may lift thelatter from the pin. The bent portion 15 of the carrying strap 5 alsoacts as a stop and when the carrying strap is moved to the left-handside, it may be urged to snap across the pin 9. When the carrying strapis moved to the right-hand side, the housing parts 1 and 2 areconsequently separated from each other, while they are joined togetherupon displacement to the left-hand side.

In the embodiment shown in FIGURES 3 to 6, the carrying strap 5 isrotatably journalled in a circular recess 16 in a ring 17 which in turnis rotatably journalled on a pin 18 rigidly secured to the wall of thehousing part 2.

The recess 16 is locally prolonged as far as the outer edge of the ring17, so that two stops 19 and 20 are formed between which the carryingstrap 5 with respect to the ring 17.

Viewed in the axial direction, the ring 17 has beside the recess 16 apart 21 of smaller diameter through which a pin 22 extendseccentrically.

For joining the two housing parts together, provision is further made ofa locking plate 2.3 which is slidably arranged in the protuberance 6 anda lock 24 which is rigidly secured to the housing part 1.

The plate 23 is provided with a recess 23 into which fits the part 21 ofthe ring 17. The pin 22 of this ring bears on the edge 26 of the recess25. The plate is further provided with a recess 27 into which the lock24 is adapted to grip, a bent edge 28. Plate 23 is also provided withtwo bent edges 29 and a part 30 around which a compression spring 31 maybe disposed. This spring urges on the edges 29 while its other end bearson the face 32 of the wall of the protuberance 6. Consequently, thisspring exerts a pressure to the left on the plate 23.

When the carrying strap is moved to the left, it engages the stop 19 ofthe ring 17. When the strap 5 is moved further to the left, the ring 19follows the movement of the strap 5, as a result of which the pin 22 isalso taken along. The plate 23 is then moved to the left. As soon as thestrap 5 abuts against the edge of the opening 7 in the protuberance 6,the plate 23 is moved further to the left under the influence of thespring 31 and takes along the pin 22 and consequently also the ring 17.During this movement of the plate 23, the latter deviates slightly fromits rectilinear path as a result of the fact that the ends of the benttongs 29 slide across the oblique faces 33 joined with the wall 6, whilethe corner 34 of the plate slides across the cam 35 which is secured tothe wall of the housing. This movement is further rendered possible bythe conical shape of the walls of the narrowed part 21 of the ring 17.After the plate 23 has reached its extreme left position (indicated bybroken lines), it is no longer within reach of the lock 24 secured tothe housing part 1 and the two housing parts may be separated. When thecarrying strap is moved to the right, it rotates first with respect tothe ring 17 until it bears on the stop 20. The ring is then taken along,as a result of which the pin 22 urges on the edge 26 of the plate andthe plate 23 is moved to the right against the pressure of the spring31. This movement is continued until the pin 22 has reached again theposition shown in FIGURE 3. The edge 36 of the hole 27 in the plate 23then grips the hook 24 and consequently pulls the housing part 1 tightlyagainst the part 2.

FIGURES 7-9 show a variant of the embodiment described hereinbefore. Inthis variant, the ring 17 is provided with a flange 37, the edge ofwhich has a recess 38. The ends of the carrying strap are provided witha fiat part 39 in which an elongated hole 40 is: provided through whichthe strap 5 is journalled on the pin 18. The elongated hole permits amovement of the strap in the longitudinal direction with respect to thering, as a result of which a pin-shaped part 41 may be introduced intothe recess 38 so that the carrying strap may be coupled with the ring17. After the coupling between the carrying strap and the ring has beenestablished, the arrangement operates in quite the same manner as thatdescribed hereinbefore.

It should be appreciated that the coupling between the carrying strap 5and the ring 17 may also be established in a different manner. Forexample, the carrying strap may be moved in an axial direction on thepin 18 while it is joined with the ring 17. It is also possible toprovide the end of the carrying strap with a pin-shaped projection whichgrips into a recess of a radially protruding flange of the ring. Theseand also other variations are possible without leaving the scope of theinvention.
